UNASSIGNED: The objective of this study was to determine the clinical, biological, and echocardiographic characteristics, and the prognosis of IE in CHD.
UNASSIGNED: It was a retrospective study, conducted from December 2010 to March 2020, at the Nephrology and Cardiology units of University Hospital in Oujda, Morocco.
UNASSIGNED: We compiled a series of 31 CHD patients having developed IE. Eleven cases (35.4%) were collected between 2010 and 2015, and 20 cases (64.6%) between 2016 and 2020. The mean age was 47 ± 19 years, 58% were male, and 25.8% of patients had diabetes. Vascular access for hemodialysis was by arteriovenous fistula, non-tunneled catheter, and tunneled catheter in 22.5%, 32.2%, and 45.2%, of the cases, respectively. About 25.8% of patients had benefited from more than two catheters (tunneled or non-tunneled) during the 3 months preceding the occurrence of IE. The mitral, tricuspid, and aortic valves were the site of IE in 41.9%, 41.9%, and 13% of the cases, respectively. Right heart IE and left heart IE were observed in 42% (13 cases) and 58% (18 cases) of cases, respectively. Blood cultures were negative in 58.1% of the cases at the time of diagnosis of IE. Staphylococcus aureus was identified in 69.2% of the cases. Mortality occurred in 54.8% of the cases.
UNASSIGNED: IE remains a severe condition in CHD patients with an increasing incidence. Rigorous prevention and screening strategies should be implemented at the hemodialysis centers.
